remove arm64 definitions of kc_vaddr_to_offset and kc_offset_to_vaddr. With the reshuffling of kernel VA space to support 52 bits, the kc_vaddr_to_offset and kc_offset_to_vaddr macros are broken, since they are based on VA_START, but VA_START no longer points to the base of the kernel virtual address space, (PAGE_OFFSET does now). fs/proc/kcore.c already has default definitions of kc_vaddr_to_offset and kc_offset_to_vaddr based on PAGE_OFFSET, so simply remove the arm64 definitions of them.
